NiTE STATES EZRA F. LANDIS, OF LANCASTER, PENNSYLVANIA.

STEAM-RADIATOR.

EPECIFICATION forming part of Letters Patent No. 351,271, dated October 19, 1886.

Application filed November 18, 1895.

T0 aZZ whom it may concern:

Be it known that I, EzRi F. LANDIS, a citizen of the United States, residing at Lancaster, in the county of Lancaster and State of Pennsylvania, have invented certain new and useful Improvements in Steam-Radiators, of which the following is a specification, reference being had therein to the accompanying drawings.

My invention relates to radiators for the passage of steam or of hot water and the ob jects of my improvements are to get a free and continuous flow of steam through continuous coils, and a free return of the water of condensation through the bottom elbow of each coil.

The invention will first be described in con nection with the drawings,and then be pointed out in the claims.

In the drawings, Figure I is a side view of a spiral radiator constructed in accordance with my invention. Fig. II is an end view of the same. Fig. III is a vertical section of a top or bottom elbow of one of the coils. Figs. IV and V are end views of a pair of male and female bottom elbows of the coil. Fig. VI is a vertical section of one of the end elbows provided with feet. Fig. VII is a side view of a radiator constructed in accordance with my invention, with the pipes running horizontally. Fig. VIII is an end view of the same. Fig. IX is a top view of a series of elbows arranged to produce a spiral radiator.

In said drawings, a represents the elbow or re turn-bends. They have their open ends bored at a slight angle to each other, and screwtapped to receive the ends of the pipes 7c and Z, the pipes Z standing vertically, while the pipes L are slightlyinelined. The end elbows are provided with feet 9, to support the radiator. Each elbow is provided with a male and female seat, j, on the sides thereof, that interlock and are packed with thick paint or other well-known means, and in the center of the seat 3 of each elbow is an opening, it, for the passage of a bolt, Z), extending the whole length of the radiator, and upon the end of the bolt a nut is placed to retain all the 01- The openings h are of larger diameter than the bolts, and form a water-course extending the entire length of the radiator, which carries the water of con- Serial No. 183,222.

densation into the T-connection c, and from there through the globe-valve E back to the boiler. Upon the last pipe k, at one end of the series, is placed a union, d, to connect said pipe with the overtlow pipe or outlet 1', Fig. 6, leading to the boiler. The water-line in the bottom elbows is indicated at N, from which it will be seen that the water will not leave the radiator until it closes sufficiently the opening h in said elbows, to prevent the steam from passing through this shorter course, and obliges it to follow its proper course, corresponding with the arrow m, up the pipe Z and down the pipe it, thus forming a perfect serpentine course for the steam, and an independent channel through the openings h for the water going back to the boiler.

In Figs. VII and VIII is shown an arrangement of horizontal pipes to connect the elbows, a series of said pipes on one side entering the elbows at right angle, while pipes on the opposite side enter therein at a more acute angle, and the whole supported on feet.

In Fig. IX the elbows a have male and female jointsj j, as heretofore described; but the openings a jto receive the ends of the pipes 7t- Z, are staggered, so that each one can be tapped squarely,in place of having each alternate one tapped at an acute angle. They are also provided with a central opening, IL, for the passage of the water of condensation and of the belt that unites them together.

Having now fully described my invention, I claim 1. In a steam radiator, the combination of pipes L Z and elbows (1, provided with lateral water-openings h, bolts passing loosely therethrough, and overflow-openings i, so arranged as to have the upper edge of the opening it substantially upon the same level as the bottom edge of the opening 1' in the bottom elbow, whereby the water of condensation in said coil seals the opening h, substantially as described.

2. In combination with a series of substantially vertical pipes, Z, and slightly inclined pipes k, the elbows a at the top and bottom ends of said pipes, receiving the ends of the pipeslat aright angle and the pipek at an acute angle, and the T-connection a at one end, substantially as and for the purpose described.
